The division of Electricity at Uppsala University is developing a wave energy converter(WEC) consisting of a linear generator connected to a bouy at the water surfacethrough a wire cable called the connection line.During extreme conditions, the wave power plant will experience forces up to 500kN, which lead to unnecessary wear and will ultimately cause the failure of theconverter. To prevent this there is a need for a damper.The wave energy converter works at a maximum efficiency when the translator?sare centered with respect to the stator. Due to tidal movements the position of thetranslator can deviate. There for a mechanical divice that will compensate for this isneeded.This report describes the further development of an earlier project where a tidalwave compensator for a wave energy converter of Seabased AB was developed.

I have together with Frimeko AB developed new hallway furniture for preschools. The background to the project is the fact that all the existing hallway furniture?s on the market today have a similar design and same features. None of the furniture stands out immediately. Companies who work with school furniture in general have been inspired by each other, and therefore is the collections monotonous.

Elitskon? is a new type of horseshoe for trotters. It is supposed to give the horse a trot that mimics the movement pattern of a horse trotting unshod. Many horses show a better trot unshod but this can only be used to a limited extent due to the great wear and tear of the hoof. The objective of this study was to evaluate whether the qualities of Elitskon? are similar to the unshod horse or the traditional aluminium horseshoe.

The title of this essay is Project: The Veil ? an investigation of the trends in the Swedish veil debate compared with the veil debate in France and Great Britain written by Cecilia Lindvall. The purpose of the paper is to analyze how the argument has been conducted by the Swedish politicians from the time when the veil was first recognized in Swedish media up until today. The questions I wanted to answer was each countries definition of the three concepts secularization, freedom of religion and multiculturalism, how Islam as a faith with Muslims has developed in Sweden, France and Great Britain and each countries integration politics with the politicians attitude towards the veil. The method being used is a qualitative study with three kind of theories for analysis; two who derives from a feminist point of view where the first one advocates for the rights of each women, the second for the rights of religious groups and a third theory which discusses different models of integration logics.

The idea behind this project came from a feed study executed two years during the lambing season. Both years wool loss was experienced. Low temperature in combination with shearing was believed to cause the wool loss the first year, while protein deficiency was believed to be the cause the second year. In the literature many causes of wool loss are described; mechanical wear, telogen effluvium, bacterial dermatitis, external parasites, wool break, scrapie, genetic causes and nutritional deficiencies are some examples. The aim of this thesis was to study causes for wool loss and how common wool loss is in Swedish sheep herds.

Today, the tourism sector is the fastest growing industry in the world and also includes one of the foremost for instance in the number of work and added tax. The sector entails a lot of positive factors but also negative consequences, such as overexploitation and wear on natural areas. However, even the visitor industry contributes to smaller localities boost by creating new jobs where depopulation occurs. This study focuses on the town Kisa in Kinda Municipality. The purpose of the study is to highlight the importance of tourism for migration to a town and to show the importance of developing sustainable destinations.In the results of this study it emerges that more job opportunities are requested by respondents for increasing Kisas attractiveness.

The surface finishing technique called black oxidation is currently being used on thetool holders made of low alloyed tool steel produced by Sandvik Coromant. Blackoxidation isn?t considered a sufficient technique because it doesn?t make the toolholders look like the quality products that they actually are. The reasoning behind thisis that the tool holders can show signs of corrosion after prolonged storing times orin countries with high humidity and temperature. The corrosion doesn?t decrease thetool holders performance, but the customers might believe otherwise.

This is a thesis for a Bachelor Degree Project, performed in the subject MechanicalEngineering. The students Roger Malmberg and Simon Hagberg have carried out adesign project on behalf of the recently established company J&D Assisting systems,located in Halmstad.The project consisted in developing J&D's first prototype of a power assisting solutionfor wheelchairs. A power assisted wheelchair combines human power, which is deliveredby the arms through the pushrims, with electrical motors, which are powered by a battery.The power assisted wheelchair is aimed at customers, who have used a regularwheelchair for a long time, but who have become weaker or just need additional powerwhen driving uphill. This kind of wheelchair will provide additional power for users,which will spare their wrists, elbow and shoulders. The product is torque sensor free andinstead it relies on the velocity.

Phosphate is a used as a surface treatment method which is used for various purposes in the industry. In this case, phosphate coated wire is used in the processes to achieve a desirable outcome. The reason to why phosphate coated wire is used in the production process is because phosphate acts as an accumulator, where it stabilizes the lubricant on the surface of the wire. Lubrication is important because it plays a major role in the roll quality and characterizes important benefits regarding the outcome.Currently, SKF has to wash away all phosphates residues after extrusion process in an operation called tumbling. The main reason for this is simply because the surface has to be completely free from lubricants and coatings till the next step of process.

Want to help making the world a better place? Do it with HypOCycle!HypOCycle is a bachelor thesis that started in September 2007. The project is owned byLars-Johan Hjertz and Erik Westerlund.HypOCycle is probably the only bike in the world that has a linear pedal movement. Themovement comes from a new engine technique that hasn?t even been brought to themarket yet.

Denna uppsats syfte är att undersöka hur arbetsvillkoren ser ut hos leverantörer i Kina som levererar produkter till västerländska företag och ställa dessa arbetsvillkor i jämförelse med de uppförandekoder som företagen har. Studien utforskar vilka områden av uppförandekoderna som är särskilt problematiska samt vilka faktorer som har inflytande på hur uppförandekoderna följs.Den tidigare forskning som finns på området är mycket begränsad och framförallt saknas studier av ett större antal fabriker. I dessa studier syns vissa samband mellan hur uppförandekoderna följs och faktorer som t ex storlek på fabriken, antal tidigare kontroller, andel av fabrikens totala kapacitet. Vår teoretiska referensram användes till att förklara varför det ser ut som det gör och vi utgick från intressentmodellen samt teori kring förändring av organisationskultur för att göra detta.För att undersöka detta fick vi tillgång till dokument från organisationen Fair Wear Foundations kontroller av arbetsförhållanden i relation till uppförandekoder hos sina leverantörer. Dessa dokument kodades sedan genom kvantitativ innehållsanalys för att få fram en bild av i hur hög utsträckning leverantörerna bryter mot uppförandekoderna vilket vi sedan kunde analysera statistiskt.Resultatet visar oss att uppförandekoderna följs i förhållandevis hög utsträckning.

This is a thesis presents a differential gear which is found in a tracked vehicle called BvS10. The tracked vehicle is manufactured by BAE Systems Hägglunds AB in Örnsköldsvik, Sweden. The differential gear has a bolted house. The differential meets the requirement specifications, but the problem is that the bolts are sheared off because of the extreme torque that the differential is exposed to resist.Previous report on the differential show pictures of bolts which have been sheared off at the threads. This report is also includes three lists that explain seven different proposals which some are approved and some are not, and the report also presents the force, tensile, and shear stress.In a bolted connection there is both axial tension stress and radial shear stress, which can lead to wear out and broken bolts.

Våta kopplingar används i automatiska transmissioner för att överföra vridmoment. De primära komponenterna i en våt koppling är de oljesmorda pappersbaserade friktionslamellerna och separationslamellerna gjorda av stål. Volvo Construction Equipment (Volvo CE) utvecklar och bygger automatiska powershifttransmissioner med våta kopplingar till sina anläggningsmaskiner. Volvo CE och Luleå Tekniska Universitet (LTU) bedriver tillsammans forskning om våta kopplingar som involverar pappersbaserade friktionsmaterial. De två vanligast förekommande materialen i produktion, i detta examensarbete benämnda som material A och B, testades i en testrigg på LTU.

To differentiate between bones from sheep (Ovis aries) and bones from of goats (Capra hircus) is a long lasting challenge for zoologists, archaeozoologists and osteologists. Especially considering archaeological remains which are often found fractured and poorly preserved due to taphonomic processes. Zeder & Pilaar?s (2010) and Zeder & Lapham?s (2010) methods of species differentiation has shown promising results when used on bones from modern sheeps and goats. This paper aims to evaluate these methods by exerting them on excavated bones from kv.

 In light of the resent surge in globalization, and the heightened competition that follows as a result of this, there has been an increase in the importance that is placed into understanding buyer behaviour. This increase has been seen since the realization that by building strong customer relationships it is much easier to reach these through the marketing communications that are put in effect. There are also a number of upsides to enlisting the customers at an early stage in product development, such as creating greater value and a stronger sense of involvement.Röhnisch is therefore trying to show a genuine interest in supplying the costumers needs as they adapt and evolve. In order to accomplish this strive towards gaining a deeper understanding into the thoughts and attitudes that precedes the buying behaviour they conduct regular surveys. To complement this, the purpose of this paper will be to determine the actual preferences and buying behaviour of the market segment that Röhnisch has chosen for themselves, and while doing so, keeping an emphasis on loyalty.
